The torque from Regal GS’s exclusive Ecotec 2.0L high-output turbocharged engine provides more launch force than the Acura TSX V-6, Audi A4 Sport, Lexus IS 250 and 350, Infiniti G25 and G37, and Volvo S60. It also delivers the highest specific output of any production engine GM has ever offered, and at 135 horsepower per liter, is the most power-dense engine ever certified by the Society of Automotive Engineers.

Buick’s exclusive Interactive Drive Control System is standard on the Regal GS, and allows drivers to choose from three operating modes – Standard, Sport and GS Mode – that change the suspension settings and steering sensitivity according to driver preferences. Regal GS also features a four-wheel independent suspension with a unique High Performance Strut (HiPer Strut) front suspension design that reduces torque steer and improves grip and cornering power.

Buick IntelliLink (later availability) uses Bluetooth or USB to connect the driver’s smart phone to a new high-resolution, full-color seven-inch touch screen display radio. IntelliLink expands on Buick’s current Bluetooth and USB capabilities to allow smart phone control via voice activation and steering wheel-mounted controls. It also enables streaming stereo audio from the phone through services such as PANDORA® Internet radio and Stitcher SmartRadio®.

IntelliLink complements the safety, security and connectivity services of OnStar, also standard on all Regal models. With a simple button touch, voice command or via a downloadable smartphone app, Regal owners can access popular OnStar services such as Turn-by-Turn navigation and Destination Download, hands-free calling, remote door unlock, vehicle diagnostics, emergency assistance and much more.

The Regal GS rides on a wheelbase of 107.8 inches (2738 mm) that delivers refined, well-balanced vehicle dynamics. It also features a four-wheel-independent suspension, with a unique High Performance Strut (HiPer Strut) front suspension design.

Drivers may choose more aggressive, performance-oriented damping characteristics through the standard Interactive Drive Control System.

Standard StabiliTrak stability control system with integrated, full-function traction control.

Interactive Drive Control System

The Regal GS is equipped with the Interactive Drive Control System, which adapts damping and other driving functions to drivers’ preferences. While the Regal Turbo offers Interactive Drive Control with the choice of a standard adaptive setting, a more comfortable Tour mode and a Sport mode, the system in the Regal GS is deliberately tuned for those who enjoy a higher level of performance:

Sport: Features a firmer level of suspension damping and reduces body roll for more agility.

GS: Readies the car for dynamic, enthusiast-level driving. Increased steering efforts provide more direct feedback to the driver, while increased damping levels ensure ultimate wheel control and reduced body roll for ultimate agility. Only the GS mode will alter the shift feel on an automatic transmission.

Efficient, proven powertrain

High-output Ecotec 2.0L turbocharged DOHC VVT engine with direct-injection technology provides acceleration of a V-6 with the fuel efficiency of a four-cylinder. EPA-estimated fuel economy is 27 mpg on the highway with the standard six-speed manual.

Output rated at 270 horsepower (201 kW) and 295 lb.-ft. of torque (400 Nm). Peak torque is achieved at a relatively low 2400 rpm; 95 percent of peak torque is available between 2,300 and 4,900 rpm.

Highest specific output of any GM production engine, and at 135 horsepower per liter, the most power-dense engine certified by SAE.

Regal GS is equipped with segment-exclusive OnStar technology, which includes the Advanced Crash Response System, emergency assistance, remote vehicle diagnostics, six months of the Directions and Connections plan for route guidance support and OnStar RemoteLink.

OnStar RemoteLink allows Regal owners with certain smartphones to download an app to start the vehicle remotely, as well as get information on the fuel tank’s level and range, the remaining oil life, current and recommended tire pressure, and lifetime average miles per gallon. In addition users can access the current odometer reading, vehicle ID (VIN) and OnStar account number, plus call a dedicated representative for advice or assistance.

Other OnStar services:

The Advanced Crash Response System uses vehicle sensors, GPS and digital cellular phone technology to summon emergency responders to a crash scene even when the vehicle’s occupants are unable to do so.
